I'm developing an app for Android, Windows Phone and IOs with the purpose of control the access of users to certain locations: First the location nfc tag is read and after that the users nfc tags are read.
The app must assure some kind of anti-cloning security (like "originality check") and UID.
Where can I obtain information about how implement such security system?
How can I use this NFC tags with IOs?
Thanks in advance.
